EF's right - a big reason I haven't gone ILDA is the fact that we use 6-12 units at our smaller shows and for our big events can end up juggling as many as 18 units before we run out of room on the trussing ... DMX programming makes everything a lot faster and easier, especially in unknown venues where we have to reprogram our scenes prior to the show to avoid (much) audience scanning...
The 2 Laserworld units we had did some pretty nice spiral effects using the preprogrammed DMX scenes, and of course were light-years smoother than our SHINP stepper units, if I wouldn't have been offered more than we paid for them they'd still be in the arsenal (those were 20k but seriously misrepresented power-wise, like under 40% of spec prior to the optics). I was thinking of using this laser in the middle of our small rack (see my avatar) not only for the color, but for the smoothness of the patterns (to lend a little more fluidity to the chases, etc) ... I'll mull it over for a day or two, I have a small show tonight and I'll try and visualize how the blue would work and see what I come up with.
